Snails without shells, also known as slugs, like to live in dark, moist environments, and the presence of slugs in the home is mostly due to the environment being too humid. The most common seasons are spring and fall, specifically from April to July when the harm is more serious. They lurk during the day and come out at night. It feeds on plants and is a common pest in agriculture. It is transformed from the snail, the body is very soft, and the shape is similar to the snail with the shell removed.
